We all expected it, and most of us still do, but it's odd that it has failed to materialize. Obama has slipped in the new poll from Newsweek and now runs even with McCain at 46-46. More interesting is his decline in both Gallup tracking polls. Those polls don't reflect the brouhaha over Clinton's RFK gaffe, so maybe he gets his bounce back this week in the race for the nomination, but it is hard to explain how Clinton has bounced back from a deficit of 16 points less than ten days ago. Also, Clinton still holds a significant lead over McCain, and she has consistently held that lead since the beginning of the month. In the Obama-McCain match up, McCain has jumped ahead by two points in what looks to be a far less stable race. But if there's one thing we know for certain, Democrats aren't going to be swayed by electability arguments. Or are they?
